Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546894, here are decompositions:

3 + 31546891 = 31546894
47 + 31546847 = 31546894
173 + 31546721 = 31546894
233 + 31546661 = 31546894
257 + 31546637 = 31546894
293 + 31546601 = 31546894
311 + 31546583 = 31546894
443 + 31546451 = 31546894

Showing the first eight; more decompositions exist.
